The stethoscope was developed by the Specialty Medical Center of the Naval Medical University in Shanghai, China, on March 23 in order to help doctors treat COVID-19 patients.
Using a traditional "in-ear" stethoscope while wearing a heavy protective suit makes it difficult to work with patients quickly and effectively.
The data collected by the stethoscope is transmitted to the headphones in the doctor's protective suit through filtering and amplification.
